A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results from the trypsin, chymotry
Maksim231197 [3]

Answer:

The possible sequence of the decapeptide is Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

Explanation:

The cyanogen bromide cleaves the carboxyl end of Met (methionine and non-peptide). Trypsin cleaves on the C-terminal of Arg and Lys, however, not on the N-terminal of Pro, which signifies that Lys is the last amino acid in T2. Hence, Met-Val-Lys----. The middle part of the sequence can be predicted from the digestion done by chymotrypsin.

The chymotrypsin cleaves on the C terminal of Phe, Trp, Tyr, however, not on the N side of Pro. CT3 exhibit Lys, Met, Tyr, Val, as Met-Val and Tyr are the initial three amino acids, therefore, Tyr must be the fourth one. Now the sequence will be Met-Val-Lys-Tyr...

CT1 possesses Ala, Arg, Phe, Pro, as chymotrypsin cleaves the C side of the Phe, thus, the last amino acid should be Phe. Also, CT1 has Ala as the first amino acid. Also, trypsin does not cleave on the N-end of Pro. Thus, the sequence of CT1 strands will be Ala-Arg-Pro-Phe.  

In CT2, chymotrypsin cleaves on the C-side of trp. Thus, the sequence of CT2 strands as Thr-Trp is found in the middle. Thus, the whole sequence of the decapeptide strand will be:  

Met-Val-Lys-Tyr-Thr-Trp-Ala-Arg-Pro-Phe.

A mother, 13 years of age, delivers a low-birth-weight neonate. The neonate is transferred to the neonatal intensive care unit.
Natalka [10]

Answer:

The excessive alcohol consumption of the mother.

Explanation:

Alcohol consumption during pregnancy harms the developing baby, the foetus. This is because alcohol passes from the mother's blood to the baby's blood and this affects the growth of the baby's cell.

This causes severe damage to the cells of the brain and the spinal cord.

FASD - Fetal Alcohol Spectrums Disorder is characterised by growth and developmental problems and it can range from mild to severe.

Example is the baby having small head, narrow eye and behavioural problems later in life.
